Definitions

  • This invention is concerned with milking animals, especially but not necessarily exclusively, cows.
  • Milking parlours can include many milking stalls in which cows are milked individually and several cows are milked in turn. It is usual for herd management purposes for the amount of milk obtained from each animal during each milking to be measured and recorded. The milk collected from an entire herd can be delivered from the milking stalls into a common storage tank which is emptied periodically. As the milk from different animals becomes mixed together in the storage tank it is necessary to avoid milk of inferior quality, such as milk from a cow suffering from mastitis, being delivered to the storage tank. This makes it desirable to include an automatic system for identifying an animal infected with mastitis so that the animal can be treated and restored to full health.
  • mastitis infection generally starts in one udder quarter and then gets transmitted to other quarters, and to enable early diagnosis, a detection system should be capable of recognising symptoms arising due to infection in a single udder quarter.
  • Milk affected by mastitis has an increased salt content and can be recognised by a conductivity sensor, and the use of conductivity sensors in modem milking plants is known.
  • a robotic milking installation for example, it is known to provide four metering chambers for measuring separately the milk from each udder of a cow, and to include a respective conductivity sensor in each metering chamber. By comparing conductivity levels a reliable judgement about milk from one udder quarter being infected can be made.
  • EP 1131996 discloses a method of automatically milking animals in which milk flow from the respective udder quarters is measured and mastitis-depending threshold values are sensed, but this method demands a separate milk flow sensor in each of the milk lines connected to the respective teat cups.
  • each milking cluster is provided with a sensor for measuring the milk flow from an udder of an animal during milking.
  • the signals generated by the sensors are fed to a processing device which determines when milk flow data deviates from an expected value, for example indicating that an animal being milked is in heat or suggesting that the animal is suffering poor health.
  • Information derived from sensors by the processing device can include:
  • EP-A-1297742 refers to a robotic milking system with several sensors, in particular a milk flow sensor, a conductivity meter, a thermometer, a component meter for the milk constituents and a quantity meter. All these measurement data are transmitted to a processing device which compares the measured values with stored reference values. A warning signal can be generated when a deviation is determined from the comparison, and combinations of measured values of different variables may be used to determine whether or not milk should be processed further.
  • the present invention aims to improve the efficiency of detecting poor animal health without necessitating the use of measuring equipment in each milk line from the teat cups.
  • the present invention provides a method of milking animals comprising measuring the total milk flow from all the teats of the udder of an animal being milked and generating data representative of the measured total milk flow rate, analysing the data to detect an abnormal milk flow from one teat indicated by a predetermined departure from a predicted relationship between the milk flow rate and the time from commencement of milking, and selecting the animal for medical inspection in the event that such a departure is detected.
  • the data is analysed to detect a departure from a predicted stepped reduction in the milk flow rate towards the end of the milking procedure for the animal, whereas in accordance with another method according to the invention (see claim 4) the analysis includes determining a peak flow rate at which the flow rate remains substantially level for a major part of the animal milking procedure, and determining the duration of the milk flow at the peak flow rate.
  • the invention also provides an apparatus for milking animals, comprising a milk meter, a plurality of milk collectors for collecting milk from respective teats of an animal and conducting the milk to the milk meter, the milk meter providing an output representative of the total milk flow from the teats, and a device for receiving data output by the milk meter and analysing the data to detect an abnormal milk flow from one teat indicated by a predetermined departure from a predicted relationship between the milk flow rate and the time from commencement of milking, the device being arranged to generate an output to signal that medical inspection of the animal is advisable in response to such a departure being detected.
  • the data receiving and analysing device is arranged to detect a departure from a predicted stepped reduction in the milk flow rate towards the end of the milking procedure for the animal.
  • One embodiment of such an apparatus relies on analysis of the data generated by a single milk meter which measures the aggregate milk flow from all four udder quarters to detect a departure from a predicted stepped reduction in the milk flow rate towards the end of the milking procedure for the animal. Steps in the milk flow curve, i.e. a graphic representative of the milk flow rate plotted against time, can be conveniently and reliably sensed by calculating the rate of change of the milk flow rate, which is indicative of the slope of the curve.
  • the data receiving and analysing device determines a peak flow rate at which the flow rate remains substantially level for a major part of the animal milking procedure, and determines the duration of the milk flow at the peak flow rate. More particularly there are determined a peak flow rate at which the total flow from the udder remains substantially constant or level, i.e. seen averaged over at least one vacuum pulse cycle for each teat, and the duration of the milk flow at the peak flow rate.
  • a reduced peak flow rate without a corresponding reduction in the peak flow duration can be indicative of an injured teat or an udder quarter suffering from mastitis.
  • a ratio of the peak flow duration to the peak flow rate is calculated, and the apparatus provides an output by which the animal is labelled for medical inspection if the calculated ratio value exceeds a predicted value.
  • the peak flow rate and the peak flow duration are each compared with respective predicted values, and an output signalling selection of an animal for medical inspection is generated if the peak flow rate departs significantly from the predicted peak flow rate, but the peak flow duration remains within certain acceptable limits of the predicted peak flow duration.
  • the predicted relationship between the milk flow rate and the time from commencement of milking is preferably derived from data collected during one or more previous milkings of the same animal and for this purpose the data receiving and analysing device may include a memory for storing the predicted relationship derived from data collected during the previous milking or milkings.
  • the milk meter preferably includes means to collect and compress milk flow data into data packages, and to transfer the data to the data receiving and analysing device at intervals.
  • the data receiving and analysing device can comprise means to decompress the data packages for analysis and/or display of the data.
  • the milk flow rate data generated during milking of an animal can additionally be employed to optimise milking conditions, such as the milking vacuum level, the period of hormone stimulation in preparation for milking, and/or the time of teat cup detachment at the end of milking, during a subsequent milking of the animal.
  • FIG. 1 Shown in Figure 1 is a milking apparatus comprising first and second teat cup clusters 1, 2 each with four teat cups 1A, 1B, 1C, 1D and 2A, 2B, 2C, 2D connected to a milk claw 3 by milk tubes 4.
  • Each milk claw is connected to a respective milk meter 5 which measures the total or aggregate milk flow received from the four teat cups of the associated teat cup cluster.
  • Milk discharged from each of the milk meters is conveyed by a pipeline 6 to a common storage tank 7, possibly via a diverter valve for diversion of milk of unacceptable quality, a milk glass and/or other equipment normally employed in milking installations.
  • Each milk meter includes a measuring unit to generate data representative of the milk flow rate, preferably averaged over at least one and ideally several milking vacuum pulse cycles to smooth out transient peaks and troughs in the milk flow.
  • the milk meter also provides a data output indicating the duration of milking from the first milk flow into the milk meter.
  • the data generated can be used by a processor incorporated in or associated with the milk meter to provide a local display at the milking stall of the prevailing milk flow rate and/or the milk yield as the milking progresses.
  • the data generated by the milk meter is also transmitted to a central processor 8, such as a computer, in which the received data is analysed and which produces an output either during or at the end of milking an animal to signify that medical inspection of the animal is advisable.
  • a central processor 8 such as a computer
  • Figure 2 illustrates a typical milk flow curve for a normal healthy teat which is shown in full line, and for an injured or infected teat, shown in broken line.
  • the total milk yield from a cow is not in itself indicative of the health status of the cow because there are many factors which influence the milk yield, including the time since the last milking, the food intake and the quality of the feed, and the general well being of the cow. Stress, general illness, poor feeding and a bad or inconsistent milking regime may result in diminished milk yields. It has now been recognised, however, that the milk flow curves can be relied upon to provide an effective indication that a cow is probably suffering from udder infection or an injured teat and is deserving of medical inspection to confirm the condition or eliminate suspicion.
  • the milk flow diminishes from the peak flow at different times for the respective teats whereby the flow curve has a stepped profile with each step having a trailing edge, depicted by the triangles in Figure 3 , coinciding with the end of the peak flow durations of the respective teats.
  • the data output by the milk meters 5 in Figure 1 will correspond to the milk flow curve shown in Figure 3 .
  • the milk flow meters measure the milk flow rate and integrate the milk flow over time to calculate the milk yield. Since there are four udder quarters and four teats, there are four distinct steps on the flow curve towards the end of the milking procedure and an analysing device can be arranged to detect and count the number of steps included in the milk flow curve.
  • the steps in the milk flow curve can be conveniently and efficiently sensed by calculating the slope of the curve, that is the rate of change of the milk flow rate. At each horizontal or level step portion the slope is close to zero, and as the curve drops from one step to the next the slope changes to sharply negative before becoming close to zero once more.
  • the slope changes can be sensed by appropriate analysis of the data received to provide an efficient and effective way of counting the number of steps in the flow curve.
  • the milk flow curve whether for an individual teat as shown in Figure 2 , or for all four udder quarters as shown in Figure 3 , has a characteristic peak flow rate and a peak flow duration.
  • the peak level or plateau of the flow curve can be estimated such as by averaging or least-square-estimating method, to eliminate transient fluctuations and arrive at a peak flow with a zero slope having a specific peak flow rate and a specific peak flow duration.
  • the peak flow duration is the time that elapses between the peak flow being reached, i.e. T 1 in Figure 3 , and the time T 2 at which the flow starts to decrease.
  • the peak flow rate and the peak flow duration can be determined accurately by the data receiving and analysing device. If one teat is injured or the corresponding udder quarter is affected by mastitis, but the other teats remain healthy, the peak flow rate is diminished with a significant factor, yet the peak flow duration will not be decreased to the same extent and may even remain unchanged, for example as shown as shown by the broken line in Figure 3 . This in contrast to the way in which the milk flow is influenced by other variable factors such as poor feeding or stress, when there is a general decrease in milk yield with peak flow duration being reduced more significantly than the peak flow rate. The peak flow rate is not directly correlated to the milk yield.
  • a ratio of the peak flow duration to peak flow rate can be calculated to give an indication that an injured or infected teat is suspected.
  • the data analysing device is arranged to make the calculation using the data received from the milk meter and to generate a signal to alert the herdsman that the animal in question should be medically inspected because a teat injury or an infection is expected. It is believed that a high level of accuracy in predicting injury or infection can be achieved by this technique for example better than 90% or 95% and possibly as high as 99% confidence. It will be beneficial if the predicted factor level is based on data recorded during one or most preferably several previous milkings of the same animal and the data receiving and analysing device can incorporate a memory for storing recorded data from earlier milkings.
  • the data receiving and analysing device can be programmed to compare the peak flow rate with a predicted flow rate and compare the peak flow duration with a predicted peak flow duration, the predicted values being determined taking into account statistical factors.
  • the peak flow duration during that milking again determined from data generated by the milk meter, does not differ significantly from, i.e. remains within acceptable limits of, the predicted peak flow duration for that milking of that particular animal, it is indicative of a strong probability that a teat is injured or an udder is infected such as by mastitis and an output can be triggered to alert the herdsman of a medical inspection of the animal being recommended.
  • the methods described above can be employed to provide reliable warnings to a herdsman that an animal is suffering from an injured teat or an infection of the udder, and that these methods can easily be implemented in existing milking parlours equipped with single milk meters for measuring the total milk flow from the four teats of an animal. Consequently the method provides a cheap alternative to installing multiple metering chambers in association with respective teat cups and/or conductivity meters, for establishing existence mastitis infections which can cause serious damage to farm business if allowed to spread unchecked due to a failure to detect the infection and treat the infected animals.
  • the data provided by the milk meter can also be utilised for other purposes in order to improve the milking conditions. It is, for example, important to remove the teat cups from the teats at the appropriate time in order to avoid milk yield being reduced, and/or the residual milk left behind causing health problems to the cow, due to the teat cup cluster being removed too early, or to avoid the milking time being extended, which may result in significant extra milking time for an entire herd, due to the cluster removal being delayed. Based on accurate milk flow rate data generated by the milk meter, the cluster can be removed reliably as soon as the flow rate falls to the level chosen for teat cup removal.
  • the data transmitted from the milk meter can be relied upon for setting other milking parameters during a subsequent milking of the same animal, such as the milking vacuum level, the period of hormone stimulation in preparation for milking, or possibly to detect oestrus.
  • the milking vacuum level the period of hormone stimulation in preparation for milking, or possibly to detect oestrus.
  • This stimulation encourages the release of Oxytocin, a hormone responsible for enabling milk let down.
  • Oxytocin a hormone responsible for enabling milk let down.
  • oestrus milk let down can be delayed because other hormones such as adrenaline may be present and block the release of oxytocin. If premilking stimulation is inadequate, the milk flow curve, instead of rising smoothly to the peak flow rate can suffer a dip before the peak flow rate is reached.
  • the data analysing device can be adapted to allow detection of such a dip in the flow curve and assist the herdsman is establishing an appropriate stimulation routine for the animal concerned at the next milking.
  • the milk flow curve can be displayed graphically for visual analysis or the data analysing device may check the data automatically and generate an output to signal the inadequate stimulation to the herdsman.
  • each milk meter includes a means, most conveniently a software programme, to compress data relating to or representative of the milk flow curve into data packages and to transfer the packaged data periodically to the data receiving and analysing device which includes means, in particular a software programme, to decompress the packaged data for analysis and or display.
  • the data receiving and analysing device is a computer which records the data and allows display of the milk flow curve produced by any selected milk meter.
